FD2200 stage 5
/ Translation of the original instructions
CLUTCH-BRAKE FOR PTO
The FD2200 4WD is provided with a multi-disc electro-hydraulic clutch for PTO (fig. 51) activated by an
electric push-button on the dashboard (fig. 2 no.8).
During work, with the PTO engaged, the friction material discs are pressed against each other by the oil
pressure. To make this happen, the working pressure is calibrated at 9,5 bar. All clutches are tested in
pressure to prevent oil leakage in the components. This construction design guarantees a long working life
and a gentle activation.
In order to meet
security requirements
, the
clutch for PTO
has a brake that stops the cutting blades within
7 seconds
from the moment the clutch is disengaged. Due to the wear of the brake friction material (fig. 51
no.3) blades may need more than 5 seconds to stop, in that case it is necessary to re-establish the distance
between the disc (fig. 51 no. 4) and the plate (no. 5) to 36.5 mm as per factory calibration. Carry out this
intervention with the machine turned off.
How to carry out the calibration:
1) Turn off the machine.
2) Loosen the counter-ring (fig. 51 no. 1) – it has a left thread.
3) Bring the distance between the disc (fig. 51 no. 4) and the plate (no. 5) to 36.5 mm by acting on the ring
(no.2).
4) Lock the counter-ring (fig. 51 no.1) against the ring (no.2).
After adjusting it, make sure that the blades stop in less than 7 seconds. If the blades take 7 or more
seconds to stop contact an Authorized Grillo Dealer because the machine does not meet the
safety
standards
and cannot be used in a safe way.
GRASS CATCHER LOCKING HOOK
The grass catcher locking hook may be adjusted with the respective screw. Please leave a small, 2 mm
clearance to make the hooking easier when closing.
